- Comment on Soldering/De-soldering USB flash-drive Plugs 4 days ago:
there’s dosdude1 soldering away on NAND chips; this should be a walk in the park even for a hobbyist.
as to macgyvering, the S in USB is for “serial” and such a connection needs very few wires, three if I’m not mistaken. so an absent USB connector could be fixed temporarily with clips and wires and such.
- Comment on bypass controller on a cheap LED strip 3 weeks ago:
sure, thanks for helping out. got now a cheap hack for lighting my abode, commercial solutions are like 6-8x the price. the CRI is crap but it’s better than nothing.
- Comment on bypass controller on a cheap LED strip 3 weeks ago:
well, I sorted it. just like @fuzzy_feeling@programming.dev and others guessed, that was the correct spot to get the power from. the issue with the fluctuating voltage was due to my shitty multimeter, checked it with another one and boom, 12 V. well, no boom, that’s just an expression.
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
that’s a solid line, I’m gonna try that. hopefully won’t burn nothing of value. thanks
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
they are. and the voltage is fluctuating (for the fade in/out light effect) when measured there. so I need to find the fucker that’s doing that and bypass it.
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
the whole thing (5 meter strip, remote, PSU/controller) cost like $5 total so I’m guessing that’s some ingenuity at play, like reusing strips meant for RGB lights and sumsuch
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
measuring difference between ground plane and the various points didn’t give me a stable voltage. the black thingy leading to the 12 V line is a SS210 (search says that’s a schottky diode) and on its output the mentioned fluctuation is happening. on its input there’s some very low voltage happening, like sub 1V (got a shitty multimeter).
if I’m understanding this correctly, then this thing boosts the voltage but the fluctuation is happening somewhere else. in other words, there is no 12 V source on this board. or?
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
they are white LEDs i.e. they shine white. the R G B leads are used to trigger them individually, for the running lights and whatnot. so when I bring 12 V to the V lead and GND to e.g. R, all the LEDs marked R (image) light up. when I then short R with G, then all R and G light up, etc.
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
it’s a RGB strip but with white LEDs.
so when I bring 12 V to the 12 V lead and then GND to the R, G, or B contact, the respective LEDs light up. when I short them all (R+G+B) all the LEDs light up.
sure, I tried it with a known good 12 V PSU and it works, but I’d like to use this one and just bypass the light-show circuitry.
- Comment on bypass controller on a cheap LED strip 4 weeks ago:
I do, and when I check the 12 V wire, it fluctuates between 12 and 5 V (that’s the blink/fade thing) so I need 12 V before it gets mangled. where am I most likely to get it from?

- Comment on Has anyone successfully self-hosted Firefox Sync? 2 months ago:
no help to you, but my god is it convoluted and complex; every year or so I look up if there’s been some change in that regard and every time I stop reading halfway through the setup instructions. maybe next year…
- Comment on PS5 Pro is struggling to improve some games, despite its power advantage 2 months ago:
Don’t follow the PS scene, but I gathered that’s an AMD APU in there? If so, what’s the desktop equivalent performance-wise?
- Comment on Store (and access) old emails 3 months ago:
I’ve set up a local mail archive with just dovecot + imap plugin. you don’t need the full mail server with postfix and whatnot, as it’s not intended to send anything anywhere, or even receive anything for that matter. it just sits there ready to be searched with thunderbird, no need for other complex solutions you’ve mentioned.
- Comment on Selfhostable notes app that encrypts the files on Disk? 4 months ago:
I wanted to write the same thing. have the notes app do the notes thing and handle encryption elsewhere.
as to apps, I suggest QOwnNotes. it’s markdown, highly configurable so you can make it minimalistic AF, stores notes in invidual files and folders. it also has a bunch functionality like syncing to nexctcolud and such, but I’d advise against it, just use it as a notes editor.
- Comment on Can the SATA-to-USB adapter affect the result of the bad sectors scan? 7 months ago:
first off, if you plan to scan the storage for bad “sectors”, that’s gonna take eons if the disk is of any considerable size. what’s more likely is you running the SMART self-test and that will work over any medium.
the cables absolutely can and do cause corruption, whether it’s plain SATA-SATA cables or the USB-SATA with their own controller on it; however, if you don’t have reason to suspect this particular cable/adapter is faulty, it’s not a worry vector per se.
- Comment on Recommendations for cheap hardware upgrade 8 months ago:
I have acknowledged that they’re that, but that’s not what OP asked for - they asked for a cheap setup (which the minis ain’t) and they intend to run a servarr instance, which implies large storage and those are both difficult and not cheap to cram into said minis.
- Comment on Recommendations for cheap hardware upgrade 8 months ago:
I don’t understand the fascination of other commenters with mini-PCs, as the mini-ness was mentioned nowhere in the OP.
any used and decomissioned old office PC, any i5/i7 is way more powerful than you’ll need for that setup. you get everything you need right in the box and you can cram it full with cheap RAM and hard disks. you get to repurpose something that’s useless as a desktop workstation and not buy more future e-waste.
yes, the mini-PCs and the Rpis are more power efficient, but the operating costs of a $30-50 PC don’t come close to the price of buying one of these mini-things, not to mention - figuring out how to run large hard disks with it.
- Comment on Radarr lists 11 months ago:
I’m really sorry for reiterating this, but what you wrote also implies that movies that weren’t on any list will also be deleted (don’t want that), along with the movies that were on a list and now aren’t (do want that). do you have first-hand experience with this?
- Comment on Radarr lists 11 months ago:
just to be 101% certain, do you have first-hand experience with this? because I’d like other movies in my library that weren’t on no list to remain where they are…
